In one of the shots, Trump was captured playing with her daughter in the rose garden ahead of the evening’s festivities held on the South Lawn.

The theme at this year’s event was “Picnic in the Park,” modeled after a summer evening in New York’s Central Park.

The first daughter definitely appeared to be enjoying herself as she and her three children watched toy sail boats float by in a fountain at the White House.

She also shared a picture from the night on her Instagram as she posed in the gorgeous dress alongside her three children. In the caption she wrote, “Family photo take #45 Lots of fun tonight at the Congressional Picnic.”
